Jaycar 1M Ohm Linear (B) Single Gang 16mm Potentiometer – 30mm D-Shaft, 0.2W

High-impedance circuit, sensor interface, or a vintage board that specifically calls for 1M linear B – and the local shop only stocks 50K. This one's the 1M value you need. Jaycar's 16mm single gang pot with the 1/4-inch D-shaft (30% milled flat) so your knob seats properly without wobble. Thirty millimetres of shaft gives you clearance for thicker panels or a bushing. 0.2W power rating. Grab it, wire it up, stop guessing at the schematic
